THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 254,894, dated March 14, 1882.

Application filed December 80, 1881. (Model) To all whom it may concern Be it known that I, GEORGE E. WILSON, a citizen of the United States, residing at Morristown, in the county of Belmont and State of 5 Ohio, have invented certain new and useful Improvements in Thill-Gouplings; and I do hereby declare the following to be a full, clear, and exact description of the'invention, such as will enable others skilled in, the art to which In it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

15 This invention relates to improvements in thill-couplings; and it consists in the construction and arrangement of the several parts, as will be hereinafter more fully described, and

I specifically pointed out in the claims.

20 In the drawings, Figure 1 is a side view;

Fig. 2, a plan; Fig. 3, a longitudinal section on line or as, Fig. 1; and Figs. 4 and 5 show details ofa coupling constructed according to my invention.

A represents the clip, Which may be secured to the axle in any ordinary manner desired. a is the bottom plate, which is provided with openings through which are passed the ends of arms of clips, which are threaded, as shown. 0 at a? are nuts placed on ends of side bars of clip. The nut cis screwed directly up against the plate a, while the nut a is screwed up against the L-bar, hereinafter described, and secures the latterbetween the nut and the plate 5 a, as shown.

b is a log extended horizontally forward from the clip A. This lug has formed through it an opening, and its inner side, around the mouth oftheopening, is countersunk, as shown,

. 0 to receive the chamt'ered end of side extension or bend of coupler c, hereinafter described.

0 is the coupler, to which the shafts may be connected in any suitable manner. Its rear end is provided with the side extension, 0,

5 the end of which extension is chamfered and rested in the countersink of lug b, as shown in Fig. 3, when it is secured by pivotal bolt, hereinafter described. Through the end and side extension of coupler is formed an opening,

50 the forward part of which I make angular, as

shown.

(I is the pivotal bolt, the shank of which, next the head, is made angular to fit the angular portion of opening through coupler c, and its opposite end is threaded to receive the nut d, which screws down against the outer side of lug b and secures the coupler and lug on clip firmly together. By the angular form of the opening through coupler and correspondingly angular portion of pivot-bolt d it will be seen that the clip and coupler can only be disconnected by unscrewing the out (1.

e is an L lock-bar, composed of the arms 6 o The arm 6 is provided with an opening fitted to pass up over the threaded end of forward arm of clip, where it is secured by not a between the latter and theplate a, as shown. The arm 6 is bent upward and resting against the side of nut (7 and locks and prevents the same from turning when the arm 0 is held by nut a as shown in Figs. 1, 2, and 3.

When desired for any purpose to nncouple the shafts, the nut (t may be loosened, when the arm e can be swung outwardly, as shown in dotted lines, Fig. 2, and the nut d can be unscrewed and the parts separated as desired.

It may sometimes be advantageous to have the opening through arm 0 of L-bar 6 made elongated, so that the arm 0 can be set flush up against side of out (1, or slightly away from the side ofsame, as circumstances may require.

) Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. The combination, with the clip and bolt .for holding the thill to the axle, of a lock-bar pivoted and turning laterally to and from the jaw of the clip and against the edge of the nut on the end of the bolt which holds the thill to the clip, substantially as set forth. 9o

2. The combination, with theclip and belt for holding the thill to the axle, ofan L-shaped lock-bar having its end cfixed and turning on the under end of the bolt which holds the clip to the axle, and turning laterally to and from 5 the jaw, and having its end 0 arranged to turn in against the jaw and close to the edge of and lock the out on the end of the bolt which holds the thill to the clip, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE E. WILSON.
